Patent CA-2237990-A1 (CA)
Title: Remplissage de contenants avec une matiere particulaire
Inventor: GRIFFIN DAVID PETER
IPC: B65B1/36
Filed: 1996-11-14
Abstract: On remplit un contenant comportant plusieurs départements (12) de plusieurs doses d'un médicament pulvérisé de manière à ce que le volume de chaque dose soit inférieur au volume du compartiment respectif auquel la dose est destinée. On introduit à l'intérieur de chaque compartiment une protubérance respective (par exemple 92), puis on remplit le compartiment de médicament (91) et l'on retire la protubérance. Ledit contenant peut prendre la forme d'une plaque à ouvertures, sur laquelle on peut procéder à l'opération de remplissage en plaçant le contenant (12) sur un lit poreux (22) en communication avec un réservoir (80) de matière particulaire, puis en faisant passer du gaz à travers le réservoir, les ouvertures du contenant (12) et le lit (22). Afin de mettre en oeuvre ledit procédé, l'invention concerne également un appareil qui comporte un réservoir (80) conçu pour contenir la matière particulaire et un ensemble de conduites (81, 92, 94) permettant de délivrer la matière particulaire du réservoir vers les compartiments dans le but de réduire le volume disponible desdits compartiments. Il est possible de maîtriser la taille des doses en sélectionnant de façon appropriée les dimensions des protubérances, et il est relativement aisé de fermer hermétiquement un contenant de type plaque, une fois rempli selon ledit procédé, en appliquant, par exemple une feuille métallique laminée.

Title: High speed traffic management control using lookup tables
Inventor: GIROUX NATALIE
IPC: H04L12/56
Filed: 1998-05-28
Abstract: A system and method for managing high speed traffic though switching elements in a digital network such as an asynchronous transfer mode (ATM) network. The system applies in particular to available bit rate (ABR) and unspecified bit rate (UBR) categories of service in an ATM network. ABR traffic incorporates resource management cells (RM) in a feed back loop from destination to source for the purpose of carrying explicit rate (ER) congestion control information.      Lookup tables are provided in order to quickly provide ER information to the RM cells. UBR traffic is subject to cell discard in the event of congestion. Lookup tables are provided in order to fairly apply an early packet discard (EPD) algorithm.
Patent CA-2243344-A1 (CA)
Inventor: GOSLING MARTIN CHARLES
IPC: F16B37/00
Filed: 1998-07-24
Abstract: A bolting system which reduces the peak stresses on the lowermost threads without the need for an insert or special thread designs. A nut having inside threads engages a bolt. The load on the nut is transferred to the work piece through a stool. The stool supports the nut near its uppermost portion, thereby placing at least a portion of the threads of the nut in tension. Stretching of the nut reduces the peak stresses on the lower threads. The nut may have a tapered outside diameter near its bottom, thereby allowing the nut to flex under load to further reduce the peak stresses on the lowermost threads.
Patent CA-2243690-A1 (CA)
Title: Metal detector target identification using flash phase analysis
Inventor: EARLE JOHN L
IPC: G01V3/11
Filed: 1998-07-22
Abstract: A flash phase analysis circuit provides parallel phase channels for simultaneously analyzing a detected signal in each of several phase windows and providing parallel outputs indicating whether a target falls in one of the phase windows. In one implementation, the parallel outputs each drive a segment of an output device to indicate the target type to the user. The flash phase analysis circuit divides a detected signal among the phase windows and then simultaneously compares the measured signal at each phase window with a reference signal. The circuit matches measured data with pre-selected phase characteristics corresponding to known targets in parallel and provides parallel output signals indicating target type.

Patent CA-2254591-A1 (CA)
Title: Method of and apparatus for multiplexing and demultiplexing digital signal streams
Inventor: BIRD PETER DANE
IPC: H04L12/66
Filed: 1998-11-26
Abstract: - Multiplexing and demultiplexing are commonplace for an efficient bandwidth utilization in telecommunications. SRTS (Synchronous Residual Time Stamp) technique is widely used for timing recovery in processing of digital signal streams. The bit stuffing is also prevalent for various purposes, one being rate adjustment. The invention performs the SRTS technique entirely digitally to monitor the rate of slower speed signal streams in relation to the rate of a higher speed stream. The digital implementation permits the use of context switching for processing a plurality of digital signal streams. As the result, hardware requirement is greatly reduced.

Patent CA-2261661-A1 (CA)
Title: Method and apparatus for continuous preparation of corrugating adhesive
Inventor: KARRAS GEORGE C
IPC: C09J103/02
Filed: 1997-07-17
Abstract: A corrugating adhesive is produced on an as needed continuous basis using a mixing chamber containing an agitator and a testing chamber including a viscosity sensor. Each adhesive ingredient is proportionally added to the mixing chamber in a total volumetric rate corresponding substantially to the rate of use in a corrugating machine. A  portion of a raw starch slurry is adjustably diverted to mix with a basic agent to control adhesive viscosity, with the amount not admixed added to the mixing chamber. Thus, the amount of adhesive made is in balance with the amount used, allowing fresh adhesive to be provided throughout a corrugating run, without a large hold up of adhesive, thus reducing capital costs and adhesive waste.
Patent CA-2262622-A1 (CA)
Title: Training weapon system
Inventor: FRANZEN ARNE
IPC: F42B8/10
Filed: 1998-05-29
Abstract: The invention relates to a training weapon system for a portable recoilless anti-armour weapon of the type which comprises a sub-calibre insert barrel (1) arranged in the bore of the launching barrel of the full-calibre weapon. In order to improve the accuracy of the system and make it more safe as well as less expensive when compared to previous systems of this type, the sub-calibre insert barrel (1) has a rifled bore to make the training projectile spin stabilized. The forward aligning member (5) for centering the insert barrel (1) is engaging the ridges of the rifles in the rifled portion of the barrel in the recoilless full calibre weapon. By such an arrangement it can be avoided that length tolerances give rise to undesired radial deviations which might result in a mis-alignment of the insert barrel (1) within the gun bore.  This could happen with the forward aligning member engaging the conical, smooth-bored firing chamber in the barrel.
